Current River Flow Updates

Latest update: 4/3/2020 -- Flows are sitting around 100 cfs. Nymph fishing is going to be the most productive method to fish the town section. Small worm, egg and mysis patterns are good point flies. Below that we like to use midge and baetis patterns sizes 18-22. Note - Sight fishing is important at the low flows. Make sure you move around and look for the fish that are willing to feed. Water is open to Green Mountain Reservoir. This is a great time to fish north of Silverthorne! Out of town use- Stoneflies, Egg patterns, worms, small mayfly and midge patters. Look for midge and BWO hatches on the warmer and cloudy days.

River Information

The Blue River through Silverthorne offers anglers the opportunity to catch a 20" trout in the morning and then shop at the Gap in the afternoon. While it may seem strange to park in an outlet mall's parking lot and get wadered up next to a family looking for some afternoon shopping, the fish that reside here can quickly refocus that distraction. This stretch of river sees considerable pressure, however the fish typically respond favorably to a good dead drift. Sight fishing opportunities are abound here and the fish are typically very aesthetically pleasing in coloration and size due to the protein rich diet provided by the dam of Dillon Reservoir.

Seasonal Conditions

In true tailwater fashion, the flies you need to catch fish here are typically the same year round. Nymphing will be the rule throughout the majority of the year, however some good summer dry fly fishing can exist given the right conditions. Midges, Baetis, Caddis and the ever aesthetically Mysis Shrimp should be your focus. Small streamers can also be protein-rich during the low light hours. This river is fishable year round and sees no shortage of anglers.
